Tota'ZZ ,whom .may f f Be it known that'I, W1LnmM,W. WAR- NnR,-a citizen of the United States, and

a specibcation. I.This invention relates to working barrels especially adapted for pumping oil and water fromwells. Y

Briefly stated, animportant object oi invention .is to provide. aworking barrel for wells having novel meansfwher'e'by sand or other granular material suspendedin the liquid is prevented :frommsettlingj on the liumping cups, thereby greatly -.prolonging the period. oi usefulness"y otthe cuprsand preventingthe loss of oil incident to the frequent yreplacing of the'cups.l clrurtherthe invention forming the sub- Y' o ject matter of this application aims to providera working barrel, which by reason of increasing the period, ohusefulnessbf vthe pumping cups will greatly reduce the labor and expense necessary to` pump the. well.l

Also the o invention-,aims .to` provide a workingy barrel wherein the :stationary and movable parts may be, pulledV to the surface as `aunit forthe. purpose, of renewingthe cups or anyjother parts lwhich may happen to be worn thereby dispensing with theqnev c essity ofentirely pulling :the tubing together withthe standingvalvey.'

l A" further. aimds to provide a working barrel rwhichis double acting and therefore pumps theliqu-id both on itsupand down strokes'.` Byreason of this A:errang-ement the oiltcan be pumped from the well in aI shorterV 40 period of time, thereby reducing `thejuel necessaryand thewear on .thema'chinery A further, Objectis to provide a: working Y barrel which. is or highly simplified vconnumerals are:` employed to designate like parts throughout the same,

through the same.

Figure 5 is a horizontal sectional View taken on line 5-5 ofl Figure 2. l

vFigure 6 .is an 'enlargeddetail sectional View through thefworkingbarrelw .o f In the vdrawing wherein for .the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 desig-` nates a welltubing which may consist of .a

pluralityV of sectionsf detachably, connected inthe yusual vand well knownmanner.4 The improved working barrelis as illustrated in Figure receivedwithingthe tubing and has itslower endv provided `with a standing valve 6v which contacts' with a vseat. nipple 7 threaded l on the lower .portiontof the tubing.

It will be Yobserved that the nipple iis less inr internal. diameter than the: internalidiameter of the tubing andr'therefore limits the .downwardmovement of thevstanding 'valve r`6 Aand associated parts; .Specifically Vthe standing'valve 6 closes thjezlower ejnd of thetubin'g 5 and thereby prevents theoil which hasrbeen pump'edinto the tubing from -vreturnjing to the s hoty `hole yin the `lower portion of th'ewell. Ofcoursethe tubingand the working valve extends to a point near the bottomof the well or it may extend into the holeishot in the. lower end of thewell by the nitro-glycerinor other explosive.l Y 1,

The improved Working barrelcomprises a lower Atubular section 8j vhaving 'itsupper end connected to a `coupling 10. As illus- `trated in Figure 2'an,.oi1 conducting pipe 1lk somewhat lessin diameter` than ythe pipe `8 is threadedinto the upper sideof the coupling: 1Q and therefore has.; communication with the; pipe 8,sofasto receive the `liquid,pumped up from the well. n

-l't might bestated that the standing valve 6, the pipe 8, thecoupling 10 and the pipe Abv the seat nipple 7.

into the pipe 8.

l1 are all stationary during the operation of the improved working barrel and the stationary parts rest upon and are supported lt will be observed that the leather rings which surround the standing valve 6 and which are securely connected to the same bulge between the ends of the standing valve and thereby provide a liquid tight connection between 'the valve and the tubing so that the oil cannot return to the shot hole.

Figure 2 illustratesv that valve cage i2 is connected to the upper portion et th standing valve 6 within the Vpipe S and 1 spherical valve ll is arranged within tlL cage for preventing the return ot the liquid through the standing valve. That is to say the ball valve 11i engages a seat within the cage l2 and due toits weight and the pressure ot the column ot liquid preventsthe return ot the liquid which has been pumped However, when a suction is created within the pipe S the ball valve lllis elevated to allow the liquid to enter the pipe.

The reciprocating or movable members of the two working barrels are operated by the sucker rod 18 connected at its lower end to the attaching shank 19 ot a valve cage 20. is illustrated particularly in Fig. 3 the valve cage 2O is threaded onto 'the' upper portion ot' a coupling member 2l and encloses a spherical valve 22. The spherical valve 22 is mounted upon an annular seat 25 and when the movable member, which is illustrated as a unit in Figure 3 is moved downwarlly the ball valve 22 is elevated so vas to allow the liquidV which has previously entered the pipe S to be discharged into the tubing.

Y Figure 3 plainly illustrates that a hollow plunger 25 is threaded into the lower portion ot the coupling 2l.. which coupling is provided with a longitudinal passage 26 which establishes communication between the hollow plunger Q and the interior ot the tubing 5. The lower portion oi' the holl'ow plunger Q5 is provided with a valve in the nature ot.' a plurality ot leather cups 28 between which a plurality ot brass Vtollowers or spacing members 29 are located. @ne ol the leatl cups 28 is engaged by a nut 30 threaded on the lower portion of the stem 3l upon which the followers and the leather cups are mounted. lt will be seen that the hollow plunger is located within the pipe 8 and that the leather cups QSwhen drawn upwardly will create a suction between the nut 30 and the standing-valve which suction will draw a quantity of liquid into the pipe 8. @n the subsequent downward movement ot the hollow plunger 25 ant the leather cups 28 the liquid previously drawn into the lower portion ot they pipe 8 will pass up through the stem 3l, the pipe 25 and into modest the tubing 5. iis previously stated, on the downward movement oft the hollow plunger 25 the valve is unseated to allow the escape O' the liquid into the tubing.

ln summarizing it will be see-n that the in'iproved working barrel introduced into the tubing 5 and that the standing valve G is engaged :with the nipple T so as to limit the downward movement of the working barrel. @t course, the standing valve 6 is hollow so that the oil may pass through the same when the suction is created by the action ol the sucker rod. llfhen it is desired to pump, the hollow plunger 25 is elevated so as to move ftheeupsQS upwardly whereupon quantity ot liquid is drawn into the lower portion or the pipe S. Gin the subse` quent downward movement olf the plunger 25 oil or other liouid thus drawn into the lower portion oi tne pipe 8 passes upwardly through the. hollow plunger and, out through the valve cage 20. r1lie continued operation ot the plunger 25 causes additional oil to enter the tubing 5 and consequentlythe oil or other liquid llows out through the upper end oit the tubing.

lt will be observed that the oil which is drawn up through the plunger Q5 and the sand ywhich is Asuspended in the oil cannot return to the cups 28. 'llhat is to say the sand or other granular matter which is pumped up through the pipe 8 and the plunger 2e cannot settle and lodge on the cups 28. Any granular matterwhich in the oil will pass out with the oil through the cage 2() and settle exteriorly of the pipe 8. 'lhis positively prevents the rapid wearing ot the leather cups 28.

By thus preventing the cups 2S trom wearing rapidly the frequent pulling et the working barrel is overcome, and consequently the labor necessary to operate the well is greatly decreased and wear on the machinery necessary to pull the working` barrel is also reduced.

The movable member ot' the working barrel is as illustrated in Figure provided with a depending traveling `tube LlO which contacts with the shoulder of the coupling 1C' and thereby limits rlownward movement ot the movable member. llowever the principal 'function ot the depending tube 40 is to ykeep sand trom working around tube 25 into cups ZSQandalso to provide pumping of oil or water on the down stroke olf the sucker rods. Figure 2 illustrates that'the upper portion of the relatively stationary pipe ll is provided with a valve in the nature ot a pair ol cups del, which cups contact with the Vinterior ot the traveling` tubev 40 and thereby causes the oil within the depending` travelino` tube el() to pass up through the tubing ilfigure 2 also illustrates that the stationary pipe ll. is provided with a le'ait spring 50 held in position 'by an attaching device 5l.

When the pressure of the'gas within the pipe 11 exceeds a predetermined point the spring 50 uncovers an opening in the stationary pipe l1 and therefore permits the 'gasto escape into the tubing. 1V f 1.
